There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{{x}^{7}sin(x)}{982} + sqrt(1)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{1}{982}x^{7}sin(x) + sqrt(1)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1}{982}x^{7}sin(x) + sqrt(1)\right)}{dx}\\=&\frac{1}{982}*7x^{6}sin(x) + \frac{1}{982}x^{7}cos(x) + 0*\frac{1}{2}^{\frac{1}{2}}\\=&\frac{7x^{6}sin(x)}{982} + \frac{x^{7}cos(x)}{982}\\ \end{split}\end{equation} \]
